AUTOMATIC ELECTRICAL ACTUATING DEVICE.

Application filed February 14, 1924. Serial No. 692,928,

T 0 all whom it may concern. Be it known that I, OSSIAN HrveLY, a citizen of the United Statcsof America, and resident of Alliance, county of Stark, and

State of Ohio, have invented certain new and useful Improvements in Automatic Electrical Actuating Devices, of which the following is a specification.

This invention relates broadly to electrical control systems, and it has forits primary object toprovide a simple and compara apparatus 1 positions. D A further object is to rovide an electrical apparatus whereby c utch mechanisms,

valves and the-like'may be shifted through the closing of a therein embodied electric circuit effected through the actuation of an associated mechanis In describing the invention in detail, reference is herein had to the accompanying Fig. 1 is a diagrammatic View of the invention, illustrating an-application thereof.

Fig. 2 is a view of the power cylinder and the -operating valve therefor.

While it will be understood that the invention is applicable to various other uses, as the shifting of clutches and other movable elements at predetermined times, it is herein exemplified as applied tothe actuation of the traveling conveyors of a sheet bar handling mechanism of the type disclosed in United States Letters Patent No.

1,503,670, dated August 5, 1924, granted to Referring to said W. J. Stoop, it being hereln shown as interposed between the rolls by which, as shown is said patent, the bars are advanced to the transfer table, and the auxiliary power cylinder by which, as shown in said patent, the conveyors are intermittently advanced. In other words, as herein shown, the invention constitutes an electrical means ,for intermittently rendering operativethe power mechanism of said patent, said means including a normally open electrical circuit arran d to be momentarily closed by each sheet ar. as a definite point in the advance of the latter. A

drawings, 1 and 2 indicate the upper and lower rolls of a pair of pinch rolls by which bars, as the bar 3 indi cated in dotted lines, are advanced. Having its end suitably pivoted, as in 'the housings 4 for said 1'ol1s, ,are the opposite ends of a rod or bar 5 having alongitudinal wing 6. Said rod or bar is located on the exit side of and parallel to the rolls and at a suitable height above the level of the pass through the rolls, as shown. The wing 6 normally occupies a vertically depending position, being maintained in such position by the force of gravity. A laterally extending crank arm 7 carried by said rod or bar has pivotally attached thereto the lower end of a substantially upright link 8' which has its opposite end similarly attached to the outer end of a pivoted switch arm 9 which in its elevated, or upwardly swung, position bridges the space between two con- "tact members or plates 10 and 11 located in an electric circuit, and which in its normal lowered position bridges the space between the contact 10 and a contact 12 located in' another electric circuit. which is normally open. I

When the front edge of a bar 3 emerges from the pinch rolls, it strikes against the depending wing 6 ofthe rod or bar 5 and swings the same to the inclined position shown in dotted lines in the figure, wherein its lower edge rests upon said bar 3. -When the rod or bar is so swung, the crank arm. 7 is raised, thereby elevating the link 8 and swinging the switch arm 9 to the elevated dotted-line-position thereof shown in the drawing. In said osition, an electric circuit is completed, w ich circuit comprises a main-conductor 13 leadingfrom a source of electric current to a stationary contact 14 forming a part of a contactor switch of an ordinary type, a conductor wire 15 which branches fromsaid conduc-' tor 13, the said contact 11, said switch arm; 9, the contact 10, a conductor wire 16,15:

contact 17, a pivoted switch 18 which -inf the normally open position of the pivoted member 19 of the aforesaid contactor switch, connects said contact 17 to a second contact 20, saidcontact 20, a conductor .wire 21 leadingvfrom said contact 20, a magnet coil 22 carried by said".pivoted switch member 19', a conductor 23 leading from said magnet coil to a post-24 carried on the to of the shell of a solenoid 25, a hori- '-zontal y arranged metallic plate or strip 4 26- disposed in seated overlying relation to the armature 27 of said solenoid, said plate or strip having one end pivotally mounted upon an uprightlug or post 28 carr ed on the top of said solenoid and having its opposite, or free, end normally resting upon said post 24, a conductor wire 29 lea ing from the pivoted endof said plate or strip 26 to a main conductor 30, the latter being connected to the aforesaid source of current. I D The closing of the aforesaid electric circuit results in energizing the magnet coil 1 22 which instantly actuates' the pivoted member 19 of the aforesaid contactor switch to swing to, a-position in which a contact member 31 carried thereby engages the stationary contact 14, thereby effecting clos- ,ing of aisecond, or shunt, electric circuit Qwhich will hereinafter bedescribed, At .the sametime, a foot portion 19 of said switch member 19 resting upon the ivoted switch 18 is swung downward su ciently to rotate the latter out of bridglng relat1on tothe'space between the contacts- 17 and 20, whereuponthe current in said shunt circuit is diverted through a resistance coil 32 interposed between the conductors 16 and 21. w

- The shunt circuit above referred to, closed as aforesaid, comprises the main line conductor 13,the engaged contacts 14 and 31, the ivoted' member 19 of the contactor switc ,a conductor 33 leading from said member to the conductor 16, the ortion of the lastmentioned conductor WlllCll is disposed intermediate said conductor 33 and the resistance coil 32, said resistance coil 32, conductor 21, magnet coil 22, conductor 23, post'24 the pivoted plate 26, conductor 29 and main line conductor 30. The closing of this circuit diverts sufiicient current through the energized magnet coil 22 tohmaintain' the engagement between thecontact .lmembers 14 and 31 when the switch-arm' 9 is shifted from ongagementwith the contact member 11 and bridges the space between contact members-10 and 12, as when the bar 3 has passed: from the rolls; Thus, a second shunt circuit is established which comprises 'main line conductor 13, the engaged contacts 14 and 31, the pivoted contactor memher 19, conductor 33, the conductor 16, contact member 10, switch arm 9, contactmember 12, a conductor 34 which leads from said contact member 12 to a contact 35, a vpivoted switch 36 which bridges the space between. said contact 35 and a contact 37,. a conductor 38 leading from the last men tioned contact, a magnet coil 39 carried b a pivoted contactor switch member 40 similar to the switch member 19, a conductor 41 leading from said coil and tapped to the conductor 23, said conductor 23, post 24, pivoted plate 26, conductor 29 and the main line conductor 30.

The closing of the circuit last above described energizes magnet coil 39 which ingage the contact 43, as just described, a

main electric circuit is established, comprising main line conductor 30, contacts 43 and 42, contactor switch member 40, a conductor 44, the coil of the solenoid 25, a conductor 45 leading from said coil to the contactor switch member 40, the last mentioned switch member, engaged contacts 31 and 14, and the main line conductor 13.

ergizes the solenoid 25, actuating the armature 27 of the latter to rise is suitably connected, as by a pivoted lever 46 and a connected rod 47, to the valve 48 to be-shifted. Consequently, elevation of said armature effects, through the intermediate mechanism, the elevation or shifting of said valve from its normal position to a position admitting fluid actuatingpressure to the ower cylinder 49. Adjacent to the end of the upward movement of the armature 27 the upper end of said armature Strikes the pivoted plate 26 and lifts'the free end of the latter from the post 24, thus breaking the electric circuit throu h the coils of the contactor switches, 'fol owing which the contactor switch members 19 and 40 instantly swing back to their normal positions, breaking the main line circuit. At the same time, the solenoid armature being released, said armature and the thereto connected valve 48 are free to move to their normal positions.

The switch mechanism comprising the pivoted member 19, magnet coil 22, contacts 14 and 31, pivoted member 18, contacts 17 and-20, and the resistance coil 32 constitutes an ordinary commercial form of contactor switch,'as does also the corresponding mechanism which includes the pivoted. member 40.
